Influence of the nature of the ligand on the structure and spectra of boron-containing iron(II) dioximates
The Moessbauer (/sup 57/Fe) and NMR (/sup 1/H, /sup 13/C, /sup 11/B) spectra of the macrobicyclic dioximates FeD/sub 3/(BF)/sub 2/, where H/sub 2/D stands for glyoxime, methylglyoxime, 1,2-cyclohexanedione dioxime (Nioxime), furildioxime, and benzil dioxime, have been investigated. The values of the isomer shifts for these compounds range from 0.31 to 0.37 mm/sec relative to sodium nitroprusside, and the Raman scattering ranges from 0.6 to 0.9 for the aliphatic oximes and is equal to approx. 0.2 for the aromatic oximes. The changes in the Raman scattering have been related to the angle of distortion of the trigonal prism. The greatest changes in the /sup 13/C and /sup 1/H NMR spectra are observed for the atoms of the substituents.
